SPECIFICATION forming part of Letters Patent No. 640,734, dated January9, 1900.

Application led October 21,1898. Serial No. 694,155. (No model.)

To all whom it may con/cern:

Beit known thatLGEoRGE LAWRENCE BEA- DELL, of Chicago, in the county ofCook and State of Illinois, have inventeda new and ImprovedGrain-Cleaner, of which the following is afull, clear, and exactdescription.

The object of the invention is to provide a new and improvedgrain-cleaner which is suitable and durable in construction, veryeffective in operation, and arranged to readily and thoroughly separatelarge matters-such as corncobs, rocks, pieces of wood, weeds, and coarsestraw-from the grain and seeds, then separate one kind of grain or seedfrom another, and finally separate small shriveled kernels of grain fromthe perfect plump kernels and graduate the latter as to size.-

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claim.

Reference is to behad to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a sectional side elevation of the improvement. Fig. 2 is atransverse section of the same on the line 2 2 in Fig. l. Fig. 3 is anenlarged plan view of the rougher, and Fig. 4 is a similar view of partof one of the interchangeable sieves or screens.

The improved grain-cleaner is provided With a vertically-disposed box orcasing A, supporting at its upper end a hopper B, through which thegrain is introduced into the casing A, the grain passing first upon aslide C, arranged transversely in an inclined position and mounted tomove to increase or decrease the opening between the lower end of theslide and the rear side of the casing, so as to feed the desired amountof grain down upon the rougher D. The upper end of the slide C extendsthrough an opening in the front of the casing A, and said upper end ofthe slide rests on a roller C' for insuring an easy movement of theslide when adjusting the same for feeding more or less grain to therougher D.

In order to move the slide, I provide the under side thereof with racksC2, in mesh with pinions C3, secured onatransversely-extending shaft C4,journaled in suitable bearings in the sides of the casing, a hand-wheelC5 being secured on one outer end of the shaft to permit the operator toturn the shaft and cause the pinions to move the racks C2, andconsequently the slide C, in the desired direction for the purposementioned.

The rougher D is inclined downwardly from the rear or back of the box tothe front thereof, and said'rougher is provided at its upper end with arod D', fitted in the sides of the boxA and forming a fulcrum for therougher D to swing upon, the desired motion being given to the rougherby a revolving wing F, hereinafter more fully described. The rougher Dis further provided with spaced bars or rods D2, extending from thefulcrum-rod D' to a rod D4 on the lower ends of the bars D2, the latterbeing spaced at both rods D and D4 by suitable washers D3 and D5, as isplainly indicated in Fig. 3. The lower end of the rougher D extends intoa spout E, leading from the front of the box or casing A, and when themachine is in operation` and the material passes upon said rougher Dthen large matters-such as corncobs, rocks, pieces of wood, weeds, andcoarse straw-readily pass down the bars D2 in to the spout E, to bedischarged through the same to the outside of the machine, the grainpassing between the bars D2 down upon an inclined bottom G, extendingfrom one side of the box to the other and from the back of the boxdownward to within a short distance of the front thereof, as is plainlyshown in Fig. l. The fulcrum Dl of the rougher is protected by anoverhanging bead A', attached to the inner face of the back of the boxA.

The lower end of the bottom G discharges the material upon a separatorH, similar in construction to the rougher D, the only difference beingthat the bars for forming the separator are spaced a less distance apartthan the bars D2 above described and shown in Fig. 3. The upper end ofsaid separator H is pivoted to the front of the box A and is protectedby a bead A?, similar to the bead A, as shown in Fig. l. The separator Hextends downwardly, the lower end reaching within a short distance ofthe back of the box A, and said separator receives a swingingmotion froma wing F', similar to the wing F and rotating with the same. For thispurpose the wings F and F are secured on shafts F2 and F3, jour- IOC)naled in the sides of the box A, and the outer ends of said shafts areprovided with sprocketwheels F4, over which passes a sprocket-chain F5,so that when one shaft is rotated the other shaft rotates with it toimparta rotary motion to the wings F and F' and swing the rougher D andthe separator H simultaneously up and down. A crank-arm F6 may beprovided for turning one of the shafts F3 F4 by hand; but pulleys andbelts may be employed for the purpose, if desired.

The separator H serves to separate one kind of grain or seed fromanother-that is, the undesirable grain or seed passes over the lower endof the separator and drops down in the box A, while the desirable grainpasses through the bars of the separator and falls upon a sieve I,inclined downwardly from the front of the box to within a suitabledistance of a deilector J, secured transversely inthe sides of the box asuitable distance from the back thereof, so as to form a channel betweenthe back and the defleotor for the passage of the material leaving thelower end of the separater I-I.

The sieve I serves to separate small and shriveled grain from the plumpkernels, and

also allows the line matter, such as dirt, to

pass through the meshes of the sieve upon an inclined bottom K,extending from the lower end of the sieve forwardly and downwardly towithin a short distance of the front of the box, so that the separatedmaterial traveling down the bottom K finally drops oi the same and downinto the box A to be removed from the lower end thereof with otherrefuse. The deliector J causespthe grain to pass upon a second. sieveI', inclined downwardly and forwardly to allow of further separation ofthe undesirable matters from the grain, said nndesirable matters passingthrough the screen upon an inclined bottom K', terminating at its lowerend upon a deliector J similar to the deiiector J. The grain passingdown the screen I' passes upon another screen I2 below and parallel tothe bottom K' and connecting at its lower end with an inclined bottomK2, parallel to and above a screen l?, extending downwardly from thedeilector J Another screen I4 receives the material f rom .the screenI3, and the material passing through the meshes of the screen I dropsupon an inclined bottom K3, parallel to the screen I4 and above thesame, and terminating at a dellector J 2 similar to the deflector JAnother bottom Kl is under the screen I4, and a screen I5 is under thebottom K4 and extends downwardly and forwardly from the deliector J 2.

It will be seen by the arrangement described that the bottoms K, K', K2,K3, and K1 and the screens I', I2, I3, I4, and I5 form a zigzag channelL, through which the material travels, to insure a gradual separation ofthe undesirable material from the plump and perfeet kernels of thegrain, the latter being finally discharged from the lower end of thescreen I's into a chute N, extending from the front of the box A. Thelower ends of the bottoms K and K2 are provided withdownwardly-extending flanges K5, which form deiectors for readilydirecting the material to the next following screens l2 and I4,respectively, the upper ends of which screens abut on the lower edges ofsaid ilanges.

The several screens from I' to l5 are fitted to slide in grooves A3,formed on the inner face ot' the sides of the box A, so that the saidscreens can be removed and interchanged for screens of different-sizedmesh, according to the nature of the material under treatment. Access ishad to said screens, for the purpose mentioned, by the removable portionA4 of the back of the box A and the removable deiiectors J, J', and J2.

It will be seen by the arrangement described that the material passedinto the hopper B is fed in desired quantities by the slide C upon therougher D, on which the large matter is separated from the material anddischarged at the outside of the machine, while the material passes uponthe separator H, on which one kind of grain or seed is separated fromthe other, the undesirable part being discharged into the box anddropping down the same to a place of discharge, while the grain passingthrough the bars of the separator passes upon the screen I and thenpasses successively to the screens I I2 lS l4 15 for a thoroughseparation of other foreign substances and small shriveled kernels ofgrain.

By having the bottoms K K' K2 K3 K4 arranged parallel to and in closeproximity to the corresponding screens l l2 Ils I4 I5, I provide acomparatively small passage or channel for the grain, thereby insuring athorough rubbing of the kernels on each otherv and a proper scouringthereof.

It is understood that by imparting a swinging motion to the rougher Dand the separator H a rapid separationof the material passing over saidrougher and separator is obtained.

By using different-sized washers D3 D5 in the construction of therougher D and sepator H, I am enabled to space the bars D2 according tothe nature of the grain under treatment. Furthermore, the constructionof the rougher and separator permits their convenient removal from thecasing whenever it is desired to change the spaced bars D2, as abovementioned.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A grain-cleaner comprising a box or casing having ahopper at its upper end, a hinged rougher in said casing and extendingin an inclined position, the said rougher discharging the coarsematerial passing over the same through an opening in the casing to theoutside thereof, a hinged separator below said rougher and inclined inan opposite direction, the said separator receiving the material passingthrough the rougher, means for imparting IOC IIO

a swinging motion to the rougher and separator, screens arranged inzigzag manner below rator being discharged between the deiieotors andthe Wall of the casing, substantially as desaid separator and receivingthe material passscribed.
